The ESP8266/ESP32 comes with modem simulator firmware, but it's confusing, verbose, and lacks a lot of the features that would make the ESP really look like a modem to a client computer. This project attempt to fix all those flaws with a custom Arduino implementation of that software.

Features

  • Your configuration can be saved to chip storage.
  • Supports multiple independent client connections
  • Includes "Stream Mode" client with TELNET codes
  • Supports PETSCII translation in Stream Mode
  • Supports all standard Hayes commands
  • Supports XON/XOFF flow control.
  • ESP32 Supports SD-card and X-Modem/Z-Modem
  • Supports NTP (Time) client to check the time.
